" The Doctor and his companions can never have a day off. Jack accidentally pushes a button that answers a distress call in the TARDIS, the doctor must answer it. When they arrive at their destination they discover that they are in a secluded Russian village. The village has been experiencing odd problems for some time now. Soon they hear of a mysterious death and the strange case of a girl who was once young and full of life who is now aged and lifeless. Eventually, special agents arrive and they do not immediately like the Doctor and his friends. But they learn to work together. Rose and Jack really play more of a role in this novel in the Doctor. I really feel that the Doctor is behind the scenes and I would like to read more chapters from his viewpoint. I feel we get a different look at Jack in this novel as he is not talked about being such a flirt in this one and just more concerned because it is the right thing to do. But I think being with Rose and the Doctor makes you a better person. The story line is very interesting and I can picture this book as part of the show. I would recommend Doctor Who- The Deviant Strain to readers who enjoy Doctor Who novels and readers who enjoy science fiction. "
